• Moved a screen update functionality to the main event loop
• Removed redundant animation threads
• Redesigned meter folders structure. Introduced naming convention for meter folders.

• Introduced a parameter which allows to switch random meters programmatically

• Implemented new linear meter movement directions (top-bottom, center-edges, edges-center)
• Implemented knob based linear meter (indicator.type = single)
• Added four new meters of the medium size (chillout, fantasy, relax, steam-punk). The meters use AI generated backgrounds.

• Fixed HTTP output for VU Meter screensaver
• Eliminated lag in multiple VU Meter types running concurrently

• Refactored the algorithms for circular and linear meters
• The changes allow to create vertical linear and circular meters
• The circular meter range can be more than 180 degrees now
• Fixed rendering issues for several default meters

• PeppyMeter can send HTTP requests with volume data to remote web servers
• PeppyMeter can receive HTTP requests and display volume data from those requests
• Added cache for needle sprites. It makes transition from one meter to another much faster. It also fixed the Pygame/SDL memory leak
• Implemented ability to embed PeppyMeter to larger screens
• New configuration parameter enables exit on touch event

• Now the meters to display can be defined as a comma separated names
• It's possible to enable/disable Double Buffering in the configuration file

• Added 8 new meters to the large, medium and small groups.
• Added new group 'wide' with resolution 1280x400px. The group has 8 new meters.

• Refactored the named pipe data source functionality. The meters became responsive
• Eliminated the startup delays
• Introduced the smooth buffer which helped to make all indicator animations smooth.
• Improved the meters' performance. Now the meters add about 7% to the CPU usage
• Added file logging

• Fixed the issues with the testing data sources (sine, saw etc)

New features:

• Fixed 'Display' output. If disabled it will be possible to output signal to a hardware only. No UI will be displaied in this case.
• Added 'PWM' output. It will allow to use LEDs and gas tubes as a hardware VU Meters.

New features:

• Added new native resolution 800x480px

New features:

• Modified named pipe data source to leverage peppyalsa ALSA plugin instead of file ALSA plugin

New features:

• Added new native resolution 320x240px
• Redesigned volume data extraction from named pipe
• Handling of data input from different audio players through ALSA file plugin
• Implemented support for output to Serial Interafce and I2C interface

PeppyMeter is a software VU Meter written in Python. It was originally developped as the new 'VU Meter' screensaver for Peppy Player. With minor modifications it became a stand-alone application. PeppyMeter gets audio data from media players (e.g. mpd) via fifo and displays current volume level in a Graphical User Interface in a form of traditional VU Meter.
